Riboswitches are non-coding RNA structures located in messenger RNAs that bind endogenous ligands, such as a specific metabolite or ion, to regulate gene expression. As such, riboswitches serve as a novel, yet largely unexploited, class of emerging drug targets. Demonstrating this potential, however, has proven difficult and is restricted to structurally… (More)

Enterococcus faecium strain 9631355 was isolated from animal sources on the basis of its resistance to the growth promotant avilamycin. The strain also exhibited high-level resistance to evernimicin, a drug undergoing evaluation as a therapeutic agent in humans. Ribosomes from strain 9631355 exhibited a dramatic reduction in evernimicin binding, shown by… (More)

Steadily increasing antifungal drug resistance and persistent high rates of fungal-associated mortality highlight the dire need for the development of novel antifungals. Characterization of inhibitors of one enzyme in the GPI anchor pathway, Gwt1, has generated interest in the exploration of targets in this pathway for further study. Utilizing a chemical… (More)

Senescent mice showed attenuation of habituation in locomotor activity and marked deficit in the motor performance requiring limb coordination. Also, the binding of 3H-diazepam to the crude synaptosomal fraction prepared from cerebral cortex of the senescent mice was significantly altered. The binding maximum (Bmax) was significantly greater in the aged… (More)

The binding of [3H] diazepam and [3H] flunitrazepam in rat cerebral cortex was not altered by either acute or chronic administration of pentylenetetrazol except in rats made to convulse 30 min before sacrifice. Rats treated for up to 6 months with doses of pentylenetetrazol which are below seizure threshold in naive rats, became increasingly sensitive to… (More)
